1.引入依赖

<dependency>
  <groupId>com.xy</groupId>
  <artifactId>xy-core-ids-boot-starter</artifactId>
  <version>2.0.0</version>
</dependency>

2.添加配置

com.xy.id.generator.zk.enable=true
com.xy.id.generator.zk.connect-string=${server-addr}:2181
com.xy.id.generator.cloud-service=ali
com.xy.id.generator.zk.username=

3.代码使用

String newBizNo = BizNoUtils.getNewBizNo(9);

4.组成说明

private static String getNewBizNo(String systemNum, Integer bizNum, Integer databaseNum, Integer tableNum, String version) {
    Preconditions.checkArgument(StringUtils.isNotBlank(systemNum) && systemNum.length() == 3, "[ID Generator]流水号生成参数错误: 系统号为固定长度[3].");

    String uid = Long.toString(idGenManager.genUniqueId());
    Preconditions.checkArgument(StringUtils.isNotBlank(uid) && uid.length() == 19, "[ID Generator]流水号生成错误: UID不能为空. ");
    String bizNumStr = StringUtils.leftPad(bizNum.toString(), 2, '0');
    String databaseNumStr = StringUtils.leftPad(databaseNum.toString(), 2, '0');
    String tableNumStr = StringUtils.leftPad(tableNum.toString(), 3, '0');
    String cloudService = EnvironmentManager.getCloudService().getValue();
    Preconditions.checkArgument(StringUtils.isNotBlank(cloudService) && cloudService.length() == 1, "[ID Generator]流水号生成参数错误: 云服务类型为固定长度[1].");
    String env = EnvironmentManager.getEnvValue();
    Preconditions.checkArgument(StringUtils.isNotBlank(env) && env.length() == 1, "[ID Generator]流水号生成参数错误: 环境为固定长度[1].");
    return StringUtils.join(new String[]{systemNum, bizNumStr, cloudService, env, version, databaseNumStr, tableNumStr, uid});
}

    Preconditions.checkArgument(StringUtils.isNotBlank(no) && no.length() == 32, "[ID Generator]流水号解析参数错误: 流水号为固定长度[32].");
    String sysNum = no.substring(0, 3);
    String bizNum = no.substring(3, 5);
    String cloudService = no.substring(5, 6);
    String env = no.substring(6, 7);
    String version = no.substring(7, 8);
    String databaseNum = no.substring(8, 10);

    map.put(BizNoPropertiesEnum.SYSTEM_NUM, Integer.valueOf(sysNum));
    map.put(BizNoPropertiesEnum.BIZ_NUM, Integer.valueOf(bizNum));

    }
